Early-dismantling formwork construction method for high-speed rail platform canopy
The invention relates to a construction method for a high-speed rail platform canopy early-dismantling formwork. The construction method comprises the steps that a plurality of auxiliary supporting systems are arranged on a first pouring section; a canopy formwork is arranged on the first pouring section; the first pouring section is poured; after the concrete of the first pouring section is cured to the first strength, the canopy formwork is moved downwards, the dripping eave formwork and the beam bottom formwork are folded, and the transverse size of the folded canopy formwork is smaller than the distance between the first auxiliary support and the second auxiliary support; the first strength is less than 100%; the canopy formwork is integrally and longitudinally moved to the next pouring section and erected, and an auxiliary supporting system is arranged on the next pouring section; pouring operation of the next pouring section is conducted; and after the concrete of the first pouring section is cured until the strength is 100%, the auxiliary supporting system is dismantled. Early dismantling construction of the canopy formwork can be achieved, the canopy formwork is integrally transferred, the maintenance waiting time is shortened, and the construction efficiency is improved.
本申请涉及一种用于高铁站台雨棚早拆模板施工方法，包括：在首个浇筑节段布置若干个辅助支撑体系；在首个浇筑节段布置雨棚模板；浇筑首个浇筑节段；待首个浇筑节段的混凝土养护至第一强度后，向下移动雨棚模板后，收叠滴水檐模板和梁底模板，使收叠后的雨棚模板的横向尺寸小于第一辅助支撑与第二辅助支撑之间的间距；所述第一强度小于100％；整体纵向移动雨棚模板至下一个浇筑节段并支模，并在下一个浇筑节段布置辅助支撑体系；进行下一浇筑节段的浇筑作业；待首个浇筑节段的混凝土养护至强度100％后，拆除辅助支撑体系。本发明能够实现雨棚模板早拆施工，整体转运雨棚模板、减少养护等待时间、提高施工效率。
